Revision summary
External determinants are systemic power, geography, economic dependence, and international institutions. Waltz and Mearsheimer emphasise anarchy and great-power threat; Keohane adds regimes and interdependence. Cox adds the hegemonic structure of ideas and production. India’s live external set includes China, Pakistan, Myanmar 2021, Afghanistan 2021, and sanctions maps. Governments still choose among constrained options, which is why multi-alignment is a policy, not a geography.
Model answer
Copper italics in this answer — like this — are the key facts. Each one is unpacked in the Facts & figures rail.
Introduction
External determinants are facts outside a State that shape what its foreign policy can attempt. They include the distribution of power, geography, economic dependence, international institutions, and the behaviour of neighbours and great powers. Domestic politics still matters. This question asks for the outside set.
Body
Systemic structure
- Kenneth Waltz’s neorealism puts anarchy and the distribution of capabilities first. A unipolar, bipolar, or multipolar setting changes alliance and nuclear choices.
- John Mearsheimer adds that a rising regional hegemon in Asia forces other States to balance or buck-pass. China’s rise is that kind of external determinant for India.
- Robert Keohane’s complex interdependence adds non-military channels: trade, finance, and regimes that constrain even strong States.
Geography and neighbourhood
- Borders, chokepoints, and the presence of unstable neighbours are standing external facts. For India: Pakistan, China, Myanmar after 2021, and Afghanistan after August 2021.
- Land-locked neighbours and island States create different demand for transit and navy.
- Extra-regional bases and navies in the Indian Ocean are part of the same map.
Economic and technological environment
- Energy prices, food prices, and semiconductor or medicine supply chains set daily diplomacy. The WTO TRIPS-COVID fight was an external legal-economic determinant.
- Sanctions regimes created by the United States or the UN Security Council shape third-party trade, as in India–Iran and India–Russia oil.
- Climate and pandemic shocks, treated as human security in 3(c), arrive from outside any one cabinet.
Institutions and ideas
- UN Charter rules, the NPT club, IMF conditionality, and climate treaties are external legal facts.
- Robert Cox stresses that world order includes ideas and production structures. A State’s foreign policy is made inside a hegemonic or post-hegemonic order, not in a vacuum.
- Diasporas and transnational media are external-social determinants that still act on capitals.
How they operate
- External determinants set the menu. They do not write every line. India still chose multi-alignment rather than a US treaty.
- Ranking matters: a border war crowds out a trade talk. A financial crisis can reverse a doctrine for a decade.
- Functionalist agencies and the EU show that some regions thicken institutions so that external determinants become shared rules. South Asia has not.
Flow diagram
Conclusion
Foreign policy is bounded by anarchy and power, by geography and neighbours, by energy and sanctions, and by international rules and hegemonic ideas. For India those bounds now include China, a thin South Asian region, and a contested American-led order. Choice remains, inside that set.

-
Are leaders then powerless?
No. External determinants set costs and opportunities. Nehru, Indira Gandhi, and later coalitions still chose among wars, treaties, and economic openings.
-
Is public opinion an external determinant?
It is mainly domestic. Diasporas and foreign media are the external edge of that pressure.

India continues to invoke its time-tested policy of strategic autonomy vis-à-vis both the United States of America and Russia by rejecting US' offer of mediation on Kashmir issue and by refusing to criticize Russia in its ongoing war against Ukraine. Comment
Indian Foreign Policy
Strategic autonomy means India will not outsource core security choices to a patron. Kashmir is treated as bilateral; U.S. mediation offers are refused, especially after terror shocks such as Pahalgam. On Ukraine, India avoids Western condemnation blocs while buying oil and keeping Russian platforms, without endorsing conquest. The two refusals share a doctrine but not the same moral file. This is NonAlignment 2.0 practice: partners, not instructors.

Indian Foreign Policy
FOIP for India is an open maritime order, not a Chinese lake or a U.S. private canal. Core partners: Japan, the United States, Australia, France and ASEAN; Quad is the sharpest minilateral. Connectivity — SAGAR, IPOI, IMEC, Chabahar, INSTC, digital public goods — is the other half of ‘assurance’. The strategy is sound; neighbourhood leakage and thin shipyard capacity make it incomplete. A portfolio of partners, not one ally, is the actual policy.

Critically examine the continuity and change in India's Palestine policy in the wake of the ongoing Israel-Hamas War.
Indian Foreign Policy
Baseline India policy was anti-colonial support for Palestine, two states, and UN voting with the South. From the 1990s–2010s India de-hyphenated and built defence and technology ties with Israel. After October 2023 India condemned Hamas’s terror quickly and kept humanitarian and two-state language as the war widened. Continuity is the diplomatic formula; change is partner hierarchy and the terror frame. Critical need: keep both sentences, because dropping either one breaks either the South or India’s own terrorism diplomacy.
